I do not want to commit my credentials file to github, and when running my app inside another enviroment such as Heroku, i run into the trouble because even though i can specify ENV variables i must provide a file path for GOOGLE_APPLICATION_CREDENTIALS, which is inconvenient because im using git to deploy to heroku
Describe the solution you'd like
Parse GOOGLE_APPLICATION_CREDENTIALS as JSON if it begins with '{', otherwise assume is a file path.
Describe alternatives you've considered
Adding additional code that reads an env var which contains the credential json, this is inconvenient because i will need to copy and paste this code for all my projects that use firebase admin
fun createApp(): FirebaseApp {
val credentials = System.getenv("FIREBASE_CONFIG")
.byteInputStream()
.use { stream -> ServiceAccountCredentials.fromStream(stream) }
val config = FirebaseOptions.builder()
.setCredentials(credentials)
.build()
return FirebaseApp.initializeApp(config)
}
